SPECIFICATION forming part of Letters Patent No. 770,469, dated September 20, 1904.

Application liled November 9, 1903. Serial No. 130,391. (No model.)

T0 all whom, t may concern:

Be it known that I, J OHN J LUCK, a citizen of the United States,and a resident of Aurora, in the county of Kane and State of illinois, have invented certain new and useful lmprovements in Composite Railway-Ties; and l do hereby declare that the following' is a full, clear, and exact description thereof, reference being' had to the accompanying' drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in composite railway-ties of that class consisting of a metallic core or frame and a molded body in which said core or frame is embedded,said body consisting' of a material which is formed or shaped while in a plastic state, such as cement or a mixture thereof, with a suitable binding material and which thereafter hardens or sets.

Among the objects of my invention is to provide railway-ties of this character of ample strength and durability to withstand the shocks and pounding' incident to the use of such' a tie and one which may be made within the limits of a cost which will enable the tie to be used as a substitute for wood railway-ties.

As shown in the drawings, Figure l is a perspective view of a railway-tie made in accordance with my invention,showing the manner of seating the rails thereon. Fig. 2 is a fragmentary longitudinal section thereof, takenv on line 2 2 of Fig. 3. Fig. 3 is a crosssection taken on line 3 3 of Fig. 2. Fig. et is a cross-section taken on line L 4 of Fig. 2. Fig. 5 is a cross-section of a modified form of the tie.

As shown in said drawings, (referring more particularly to Figs. l to 4t, inclusive,)A designates as a whole a railway-tie made in accordance with my invention, and B B the trackrails supported thereon. rlhe tie, as shown more clearly in Figs. 3 and 4, consists principally of a longitudinal Ametallic core or frame A and a surrounding bodyA, in which said core is embedded. Said body is molded and is made of a material which is applied to the core or frame when in a plastic state and which hardens and sets thereon to constitute a rigid continuous structure, the core or frame strengthening the body A2 and constitutinga means for stifi'ening the tie as a whole. Said core A/ thus embedded in the molded body is shown as made of lvl shape in cross-section and comprising two substantially parallel vertical side members a e and an intermediate longitudinally-folded connecting' member d of V shape, which is connected with the lower margins of the side members. The particular cross-section of the core may be varied; but the form herein shown is a preferred one, as it possesses great rigidity when embedded in the molded tie-body to resist vertical stress.

The tie is provided near its ends with metallic rail-seats, which are suitably secured to or embedded. in the molded body of the tie. As herein shown, the rail-seats are formed on metal bands C, which partially surround the tie near the ends thereof and the upper members c of which are flush with the upper face of the tie and providedwith depressed railseats d, in which the base-flanges of the rails rest. The side members c2 c? and the bottom members c of said bands are herein shown as embedded in or covered by the molded material of the tie-body, and preferably the said side and bottom portions of the bands are perforated, as indicated in Fig. 3, so as to join the thickness or layer of the molded material outside the bands to the parts of said body within the same.

in the form of device shown in Figs. 3 and 4; the metal core A is located at the top of the tie, and the upper margins of the side members a of said core bear against the top members o of the rail-seat bands C, as clearly shown in Fig. i). in some cases the parts on which the rail-seats are formed need ,not have the form of a band. The band form of railseat is a desirable one, however, when employed in connection with the other structural features hereinafter described.

The core shown in Figs. l to Il, inclusive, as located in the upper part of the tie-body, with the upper margins of its side members bearing against the top members of the railscat bands C, is directly supported from the lower members c of said bands by means of a plurality of posts or pillars l) D, which rest IOO at their lower ends on the lower members of the bands and support at their upper ends the core through the medium of cap-plates D', resting on said posts. This construction affords. a metallic support just beneath the rails and upon which the weight of the rolling-stock is received and prevents the pounding of the rolling-stock from disintegrating the molded tie-body at these points. The side and intermediate members of the core are shown as provided with openings a2, and through said holes the material of the tiebody on all sides of said core are joined. rElie metal punched from said member to form the holes is formed to constitute iianges to surround the holes, whereby the presence of the holes does not weaken the core. The rails are shown in said Figs. l to 4 as being fastened to the tie by means of bolts E E, one on each side of the rail and each extending diagonally from the top face of the tie and protruding at its lower end through the lower part of the side of the tie. Said bolts extend at their upper ends through the top members of the rail-seat bands and at their lower ends through the side members of said bands, whereby a strong anchor is afforded for the bolts. The upper ends of said bolts are provided with transverse heads e, which overlap the base-flanges of the rails and also overiie the upper or seat member of the band laterally outside of the shanks of the bolts. Said bolts are provided at their lower ends with nuts'e', by which the bolts are drawn downwardly to clamp the rails on their seats, and angle-washers areinterposed between the nuts and tie. The bolts extend through the central fold a. ofthe core A, and preferably each bolt lies against the lower surface of one of the oblique members of the connecting part of the core, thus strengthening the tie as a whole when the bolts are fastened in place. The oblique arrangement of the rail-fastening bolts is an advantageous one, as it enables the bolts to be withdrawn from the tie when desired without disturbing the setting of the tie. It will be observed that the capplates D', supported on the pillars or posts D and which in turn support the core, are located between the two rail-holding bolts near each end of the tie, Fig. 2.

In Fig. 5 the bands F, corresponding with the bands C of the previousiy-described construction and the upper members of which constitute the rail-seats, completely surround the tie and are iiush at the side and bottom parts thereof with the side and bottom faces of the tie. 1n this construction also the core A is located more nearly centrally of the molded tie-body, so that the upper margins of theside members of said core do not rest against the upper members of the rail-seat bands. The tie is reinforced just beneath the rail-seats in this construction by means of pillars or posts Gr, which are made of a length to extend from the upper to the lower members of the band and constitute continuous metal structures on which the load brought on the rail is received. rlhe rail-holding bolts H pass vertically through the tie shown in Fig. centrally thereof, and through the arch angle of the folded connecting members a of the core. Said bolts are inserted through the tie from the bottom thereof, and the nuts /L of said bolts overlap the base-Hanges of the rails, whereby the rail is clamped in place. Preferably the lower members of said railseat bands F are formed to provide sockets to receive the heads of the bolts, whereby the bolts are prevented from rotating when the nuts are turned down thereon. in Fig. is further reinforced by one or more layers of wire screen or netting I, adapted to extend from end to end thereof. The construction shown in the previously-described construction may also be provided with such reinforcing netting or screens.

'in forming the tie the several metal parts of the tie are placed in proper positions relatively to each other in a suitable form or trough-like box, and thereafter the plastic material from which the body is made is poured into the form or trough around the said metal parts and allowed to. harden thereon. The rail-holding bolts will also occupy their proper relative positions to the other metal parts of the tie before the plastic material forming the molded body is formed thereover, so that when said plastic material sets properly-located permanent openings are formed in the tie to receive. the bolts.

rihe structural details of the tie may be varied otherwise than herein suggested without departing from the sprit of my invention, andldo not wish to be limited thereto except as hereinafter made the subject of specific claims.
